Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Is there any way (except of ScaleMP) to take many pysical PCs (nodes) and install a single virtual machine that will use all the processors & memory of all those nodes?
As far as I know VMware has it's hypervisor that called "ESX" that should be installed on each physical machine (node) and the vCenter make it possible clustering between all the ESXs (all the nodes) and than it possible (again as far as I know) to create virtual machine that uses all the nodes's hardwares(cpu, memory, etc).
Then i thought, if it's really possible via VMware, does somebody knows how to do the same via Xen for example?
So, do you know about an other way to make it work?
What I actually need is make Matlab work on many physical PCs. ATM my matlab works on all the cores in my PC, thats why I wanted to create single OS that use many physical PCs resources.
it's called a beowulf cluster. I don't know if that still exists. Google it...
Took the words from my fingers. And yes, Beowulf is alive and well (bestill my heart!). It's located here http://www.beowulf.org/
What you are attempting to do is not possible on any current virtualized platform, and to be honest, violates all HA best practices. You'd be much wiser to run many "node" VMs on clusters of ESX servers.
